Using a rangefinder to determine the height of Steamboat Geyser
In the first few minutes of Steamboat's eruptions, it has often been measured well over 300 ft. with a few exceptional eruptions measured by visitors at over 400 ft.! In this example, done using a rangefinder by a Yellowstone National Park ranger, it comes in at 334.9 ft. For comparison, the Lower Falls of the Yellowstone is about 308 ft.

The Raspberry Shake 4D (RS4D)
The Raspberry Shake 4D (RS4D) is a personal seismograph with a vertical-component velocity transducer, and three-component (vertical, north-south, and east-west) accelerometer. A Raspberry Pi, which is a computer about the size of a credit card, powers the RS4D unit, which is about the size of a can of Spam.

No significant changes at Kīlauea's summit water lake
An HVO geologist collects GPS data on the western rim of Kīlauea's summit caldera. The geologist is standing upon a thick sequence of tephra deposits formed during explosive eruptions at Kīlauea's summit between about 1500 CE and the early 19th century.
